IBM® Lotus Notes® Traveler supports running on multiple Domino® partition servers on the same physical machine. The server must be configured to avoid port conflicts among the partition instances.
When you set up a Domino partitioned server, it is usually best to assign a separate IP address to each partition and use a separate NIC for each. Using a separate NIC for each address can make the computer's I/O much faster and since each partition is using a separate address, port conflicts are avoided. For information on setting up Domino to bind to separate IP addresses, see the topic "Partitioned servers and IP addresses" in the latest version of the Domino Administrator documentation in this information center.
If you are not going to use a separate IP address for each Domino partition, then you will need to use port mapping and configure your Lotus Notes Traveler partitions to use unique port numbers for its services.
Use the following steps to configure unique port numbers:
